Along the way, the pipeline would cross portions of the Ponca Trail of Tears in northern and central Nebraska. That's the route the Poncas were forced to take when the federal government ordered them to move to present-day Oklahoma in 1877.

The connection has Bold Nebraska seeking permission for Ponca citizens to participate in Keystone XL proceedings. The activist group delivered petitions to the Nebraska Public Service Commission on Wednesday, the deadline to file as intervenors.

“Bold is proud to stand with the many brave Nebraskans who have been fighting the Keystone XL pipeline for years,” attorney Ken Winston said in a press release. “We are also proud to stand up for the legal rights of many people opposing this environmental nightmare whose voices might not otherwise be heard in this process.

The Ponca Tribe is hosting a Remembrance Walk to commemorate the 140th anniversary of its forced removal. The event starts April 29 in Niobrara, in the northern part of the state, and concludes May 11 in Barneston, in the southern part.

“As we mark the 140th anniversary of the forced removal of the Ponca Nation, we honor our ancestors who have gone before us and commemorate their sacrifice and loss while also celebrating where we are as a nation today and look forward for our future generations,” Chairman Larry Wright Jr. said earlier this week.
